APPARATUS FOR VENTILATING CARS.

SPECIFICATION forming part of Letters lFatwat No. 526,702, dated October 2, 1894. Application filed December 1, 1893. Serial No. 492,516. (No model.)

To aZZ whom it may concern.' Y

Be 1t known that I, GILES A. GEER, of Utica,

p in the county of Oneida and State of New York, have invented certain new and useful Improvements in Apparatus for Ventilating (Lars; and I do hereby declare that the follow-` in g 1s afull, clear, and exact description of the 1n vention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanylng drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

My invention relates to an improvement in apparatus for ventilatin g cars.

The object is to supply fresh air for ventilat'ing purposes to a car in motion, and at the same time free the air thus supplied from dust and impurities, and at the same time regulating automatically the supply of air and thoroughly distribute it in the interior of the car. By an additional appliance, I may also wash or cool the air as desired.

In the drawings, Figure l shows a side view of a portion of the apparatus in connection with a section of car, showing the distributing portion of the apparatus located therein; the figure being broken to shorten or reduce its size. Fig. 2 shows a cross section of the receiver taken on line I-J of Fig. 1, on a larger scale. Fig. 3 shows in connection with a section of car the air passage or conductor for conveying the air into the interior of the'car and distributing it. Fig. 4 shows a longitudinal, vertical, central section of the settling or clearing chamber together with the portion ofthe apparatus attached to either end thereof. Fig. 5 shows a cross section of the settling chamber taken on line A--B of Fig. 4. Fig. 6 shows a portion of the settling chamber as it would appear with one of the sides' removed. Fig. 7 shows an end view of `the apparatus as located under a car, showing the two receivers at either side of the car,

the settling chamber suspended under the middle of the car and the air tubes leading from the receiver to 4the settling chamber. Fig. 8 shows a section on iine C-D of Fig. 4:. Fig. 9shows aseotion of the air tube or conductor taken on line E--F of Fig. 7. Fig. 10

`shows an end view of the settling chamber `with the apparatus mounted thereon, being Y the opposite end from that seen in Fig. 7,

with two of the conductor pipes or air passages taken on a section at G-II of Fig. 4. Fig. 1l shows a plan View from the under side of the apparatus as arranged on the under side of the car.

Referring more particularly to the reference letters and numerals in a morespecific description of the device, I provide on the under sider of a car A suspended therefrom adjacent to the sides, receivers B, B. These receivers are of the form shown in cross section in Fig. 2, having openings l and 2 to the atmosphere with a swing door or valve 3 located between the openings l and 2 and pivoted at 4 ou a vertical pivot at its outer side. The swinging edge of the door or valve 3 plays between the edges of the walls 5 and 6 ot' the receiver.

To the side of the receiver B toward the central line of the car, is attached one end of the V-shaped air passage or conductor 7. The air tubes or passages 7 extend from the receiver B on a downwardly sloping incline to the end of the settling chamber C. The lower V-shaped corner 7a of the tube 7 does not register exactly with the side of the chamber C, but projects slightly below leaving an opening at 8 for the escape of cinders and dirt. The tubes or passages 7 from the receivers B at either side of the car communicate at the settling chamber with the openings 9-9 inthe opposite sides thereof. These openings are partitioned off from the end of the chamber C by the partition consisting of the two parts 10a and 10h; the lower portion extending up from the bottom to about the central horizontal line of the chamber and the portion 10b from the upper edge of this nearly to the top of the chamber on an incline. On the middle portion of the partition 10b is provided a gable Il. In this gable is suspended from a horizontal pivot a swinging valvel2; the lower end of which plays in the opening 43 between the inner ends of the bottoms 13--13 of the air passages 14 extending from the openings 9 in the side of the chamber. The chamber C is provided, as shown at 15, with a V-shaped bottom, and in the portion of the chamber between the partition l0a and the end of the chamber is provided a series of small openings 16 for the escape of dirt and cinders. At the lower edge of the inclined ICO partition 10b on the side toward the body of the chamber is provided a V-shaped chute 17 which concentrates what dirt and cinders may be deposited on and shake olf from therpartition 101 at one of the openin gs 16 where they will escape at the same time removing themy ned through under the body portion'C thereof andv in the body portion are provided a series of inclined bottoms 20-20, each of which terminates at a small opening 21 in the V-shaped bottom and allows what dirt and cinders that may have entered the device thus far to escape and be discharged.

In the end of the head 22 of the settling chamber along the upper edge thereof is provided a few holes or perforatons 23 to allow the smoke and gases that have arisen to the top chamber in the slow passage of the air through the same, to escape to the open atmosphere and not pass with the air into the car. From the body C of the chamber the desirable portion of the air passes through an opening at 24 into a valve chamber 25 in which is suspended from a pivot at 26 a conoidal shaped valve 27` with its base end opposed to the opening 24 which is larger than the base end, and its apex end adapted to play through an opening 28 in the opposite wall. of the valve chamber. Onthe base end of the valve I provide a pocket 27 a for weighting the valve; The swinging movement of this valveis limited by the apex end coming in contact with a stop 29.

Attached on the inclined wall of the valve chamber is a semi-circular chamber 30 which contains the cut-0E valve 3l; the valve being mounted on a shaft 32 which extends to the outside and is provided with a worm gear A33 in which engages the Worm 34 by which the valve is operated. The shaft of the worm 34 may extend to the interior of the car, as shown, or to any other desired point from which it is desirable to operate'this valve.

Communicating with the valve chamber 30 are two exit openings 35 and 36. To the exit opening 36 is attached a pipe 36a which may extend to an ice box or cooling chamber 37 and the return pipe from this box is shown at 38. From the exitv opening 35 also extend passage-ways 39 toopposite sides of the car wherethey enter the car and are attached to theperforated pipes 40 extending along the sides of the car for distributing the air throughout the length of the' car. The distributing pipe 40 is preferably located between two' radiating steam pipes 41-41 and the perforations-shown at a are in aposition to direct the blast of air on to theradiating pipe.

` through the openings 23.

As a car equipped with the apparatus as herein shown is moved forward, the atmospheric pressure swings the valve 3 so as to close one or the other of the openings 1 or 2 in the receiver and the air enters through the other, being deliected by the door or valve and passes thence into thel passage-way or tube 7 to the box or chamberbC. If an equal amount of air is received from the two receivers on both sides the valve 12 will remain suspended in its normal and vertical position and the air will circulate, as shown by the arrowsin Fig..5 passing from the triangular conductor 7 throughthe opening 9 into the passage-way 42 below the partitions 13 and thence as indicated'by the arrowsl in Fig. 6 up behind the inclined partition 18 and over the top of the same and through the perforated partition 19 as also indicated by the arrows.

In case an unequal amount of air is received from the two receivers B, B on opposite sides of the car, the valve 12 will be swung by the atmospheric pressure so as to accommodate the greater amount of air received from one source than the other, and in some cases may even shut off one of the openings 14 entirely. By this arrangement the air entering one receiver is not able to escape through the other receiver in case of an unequal pressure, but must pass through the apparatus in the manner intended by its construction. After passing the partition 19, the air, by reason of the greater area, circulates slowly through the body C and any dust or cinders that may have been carried thus far will settle onto the inclines 20 and by the jar from the car be worked out through the openings 21 in the bottom; also during the slow passage of the air through the body C of the settling chamber, the smoke and gases carried bylthe'- air are allowed to rise and'escape The desirable portionA ofthe air passes on through the opening 24 and theopening 28 and depending on the point to which the valve 31 is adj usted, either through the box 37 with its connecting pipes into the interior of the car or directly through the escape opening 35 and connecting pipes into the interior of the car, or partially through each of these passage-ways. In the car the air is distributed from the perforated pipe 40 as before described.

I may modify the construction of the device byplacing the perforated partition 19 on an incline, as shown at 0c, and other variations and modifications in and from the construction herein described may be made without departing from the equivalents of my construction.
